CTD profile data (97 casts) were collected in the northeast Bering Sea and Chukchi Sea from the Fishing Vessel Bristol Explorer (cruise BE1301) during the Arctic Ecosystem Integrated Survey (Arctic EIS) pelagic fish survey, August 6 to September 27, 2013. CTD casts occurred at trawl survey stations and along transactions ~15 nm apart. Northern Bering Sea (NBS), stations were from 60°N and Bering Strait; Chukchi Sea stations sat between the Bering Strait and 72.5°N. The cruise was split into 3 legs, with leg 1 sampling in the southern Chukchi Sea, leg 2 in the northern Chukchi Sea and leg 3 in the NBS.

Profile data and water samples were collected by NOAA, Alaska Fisheries Science Center (AFSC) as a part of the Ecosystems & Fisheries-Oceanography Coordinated Investigations (EcoFOCI) program in collaboration with the Pacific Marine Environmental Laboratory (PMEL). Profile variables include temperature (°C), salinity, chlorophyll fluorescence (ugrams/l), oxygen concentration (umol/kg), transmission (percent), photosynthetic available radiation (PAR, microEinsteins/m^2 s) and calculated values Sigma-T (kg m-3) and oxygen percent saturation (percent). Fewer profile variables were collected on leg 1 due to failed primary CTD and use of backup that did not contain all sensors, limiting water sampling to 4 depth. The CTD issue was solved for legs 2 & 3. On leg 3 ship flooding caused damage to freezers and loss of some discrete nutrient samples and all discrete oxygen and chlorophyll samples (see included cruise report). This data set contains 1-meter-averaged water-column profile data. Profile data from CTD instruments were processed at NOAA/PMEL/EcoFOCI using standard techniques.

Purpose Scientists with the National Oceanic and Atmospheric Administration’s (NOAA), Alaska Fisheries Science Center (AFSC) conducted the Arctic Ecosystem Integrated Survey (Arctic EIS) within the Northern Bering Sea (NBS) and Chukchi Sea (CS) from August 1 to September 29, 2012. The survey was designed to provide an ecosystem baseline assessment to assist efforts to evaluate effects of climate change and oil and gas development in Arctic marine ecosystems. The purpose of the survey was to collect a broad range of marine ecosystem characteristics including physical and biological oceanographic data, Arctic marine food webs, and species characteristic of the NBS and CS regions to better understand the structure and function of these ecosystems. Data were collected at trawl stations and along-track.

Processing Steps
  • Parameter or Variable: WATER TEMPERATURE (measured); Units: degrees C; Observation Category: in situ; Sampling Instrument: SeaBird SBE-9 CTD; Sampling and Analyzing Method: At each CTD location, the rosette was lowered to 10 meters to equilibrate, brought to surface, then deployed to a close-to-bottom depth, at a rate of ~30m/minute, and ~50m/minute below ~150 meters depth. Profiles were collected on the downcast using dual SeaBird temperature sensors calibrated to ITS-90 temperature.; Data Quality Method: Data were processed and calibrations applied using SeaBird Seasoft software and pre- and post-cruise calibration data. Post-processing at PMEL included filtering extreme outliers and extrapolation of top 3-10 meters to the surface.
